DYElNG-NIACHINE.

SPECIFICATION forming part of Letters Patent No. 782,147, dated February '7, 1905,

1904. Serial No. 202,131.

To rt/Z H'wm, if 'nutll/ (forte/177e:

Be it known that l, JULIUsLEIsEL, a citizen ofthe United States, and a resident of Charlotte. in the county of Mecklenburg and State of North Carolina, have invented a new and Improved Dyeing-Machine, of which the following is a full, clear, and exact description.

The invention relates to machines for dyeing cotton and wool in the raw or in the manufactured state.

The object of the invention is to provide a new and improved d veing-machine arranged to keep the material submerged, to prevent the material from coming in contact with the air d uring the dyeing' operation, to carry on the dyeing operation economically both in time and labor, to expedite unload ing of the machine after the material is dyed and to remove foreign and insoluble mattei' from the dyeing liquor during the process of dyeing, to facilitate the circulation of the dyeing' liquor through the material, and to prevent uneven and spotted shades in the dyed material.

The invention consists of novel features and parts and combinations of the same, as will be more fully described hereinafter and then pointed out in the claims.

A practical embodiment of the invention is represented in the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a side elevation of the improvement as more especially designed for dyeing raw cotton or cotton hosiery and yarns, the parts of the machine being' in position for unloading'. Fig. Q isa sectional side elevation of the same. Fig. 3 is a like view of the same on the line 3 3 of Fig. 6, showing the parts in position during the dyeing operation. Fig. is a transverse section of the same on the line 44: of Fig. 3. Fig. is a sectional plan view of the same on the line 5 5 of Fig. 3. Fig. G is a transverse section of the improvement on the line 6 6 of Fig. 3. Fig. 'T is an enlarged plan view of the driving-gear for the drums. Fig. S is a tranverse section of part ofthe same on the line 8 8 of Fig. T. Fig. 9 is an enlarged face view of the d riving-gear for the drums. Fig. l0 is a side elevation of the retaining-arm for the shifting-lever. Fig. ll is an enlarged plan view of the shiftingmechanism for connecting and disconnecting the two sets of drums. Fig. l2 is a sectional side elevation of the same on the line 1212 of Fig. ll. and Fig. 13 is an enlarged side elevation of the locking device for the swing-frame supporting the cover.

A vat A of rectangular or other suitable shape is provided a distance above its bottom A with lugs A2 for supporting a false perforated bottom B, which forms with the said vat-bottom A a circulating-space or chamber A for the water, dye liquor, or other liquid, as hereinafter more fully described. Thematerial C to be dyed rests on the false perforated bottom B and is engaged on top by a perforated cover l) to conline the material C between the false bottom B and the said cover D a distance below the level of the liquor in the vat, as plainly indicated in Figs. 3 and 4. An overflow-pipe E rises through a well F in the bottom A of the vat and its circulatingspace, and this overflow-pipe passes loosely through the false perforated bottom B, the material C, and the cover D to extend with its upper end a distance above the said cover and a short distance below the top of the vat A. A perforated cap E closes the upper end of the overflow-pipe E to allow ready passage of the water or dye liquor, but to prevent the material O from falling into the overflowpipe on placing the material in position in the vat and onto the false bottom B at the time the cover D is out of the vat and stands in a vertical position, as indicated in Figs. l and 9.

The overflow-pipe E is connected at its outer or dischargi-i end E" with a \f'alvecasing Gr, containing a valve (i, and connected with the inlet H of a circulating-pump H of any approvedconstruction. Thecirculating-1mmp H shown in the drawings is of the rotary type, and its shaft H2 is driven by an engine or other motor H3. The discharge H" of the circulating-pump H is connected with circulating-pipes l, from which extend nozzles l.

passing through the bottom A into the circulating-space A. 'lhe nozzles l/ are preferably four in number and are grouped around i the well F, as indicated in Fig. 5, and arl i l i i l i l l l ranged to discharge horizontally into the circulating space or chamber A3 in such a manner that the liquid in the circulating-space A3 is caused to travel in a circular path around the well F for the foreign` insoluble, or other extraneous matter in the liquid to gravitate toward the well F to finally drop into the same.

AAs shown in Fig'. 5, the outlets of the nozzles I stand at angles one to the other so that one nozzle discharges in an oblique outward direction against one side of the tank for liquid to travel toward the next adjacent side and to the next adjacent nozzle, which by its discharge, acts on the liquid in the same manner to force the latter around in the circulating space or chamber A3. The outlet H4 of the circulating-pump contains a valve for closing the outlet to the nozzle-pipes l and from the said outlet leads a pipe J, having a valve J to an overhead tank J2 for storing the dye liquor.

The well F has an annular perforated wall F, rising in the circulating-space A2, and the top yof the said wall forms a rest or support for the middle portion of the false bottom B to assist in sustaining the load on the said false bottom. The lower portion of the well F is connected by an outlet F2 with the valvecasing Gr a distance above the discharge end E2, and when it is desired to discharge the extraneous matter from the well F the valve Gr is raised by the operator to an uppermost position, as shown in Fig. 2. The lower end of the valve-casingG is provided with a valveseat G2, opening to the outside for discharging the extraneous matter from the valve-casing G at the time the valve is in the uppermost position mentioned. The valve G is hollow, closed at the bottom and open at the top, and provided in its side with a port G3 for registering either with thedischarge end E2 of the overflow-pipe E or with the outlet F2 of the well F. When the valve (ur is in the position shown in Fig. 3, the overflow-pipe E is connected by way of the valve-casing' Gr and its valve G with the circulating-pump, and when the valve is now opened, the Valve J closed, and the circulating pump started then the liquid flowing into the overiiow-pipe E is forced by the circulating-pump H, pipes I, and nozzles 1 into the circulatingspace for the liquor to rise through the material C to dye the same and again overflow into the pipe E to be returned into the vat by the circulating-pump H. Then the valve H5 is closed, the valve J opened, and the valve G raised to bring the port G3 in register with the outlet F2 of the well F, then the circulating-pump draws the liquor from the vat by way of the well F and forces it up into the storage-tank J2 for further use.

ln order to heat the liquid in the vat A, l prefer to use a steam-heating pipe K, arranged in the circulating space or chamber A2 and connected with a suitablesteam-supply.

The false perforated bottom B is adapted to be raised and lowered in the vat-and swung into an inclined or discharging position, as shown in Figs. l and 2, and for this purpose the following device is provided: The righthand side of the false perforated bottom B is hung at or near its corners on the ends of ropes or chains L and L, and similar' ropes or chains L2 and L3 are connected with the corners at the left-hand side of the said bottom. The ropes or chains L, L', L2, and L3 extend upwardly and pass over pulleys L4, carried by an overhead framework A", attached to the vat A, and the said ropes or chains then extend downward and wind on drums N, N, N2, and N2, respectively, as plainly indicated in Fig. 5. The winding-drums N and N are secured on shafts N2 and N2, journaled in suitable bearings carried by the front and rear sides of the vat A, and thedrums N2 and N3 are secured on ashaft No, extending transversely and journaled in suitable bearings attached to the left-hand side of the vat A, as plainly indicated in Fig. 5. On the drums N and N or on their shafts N2 and N5 are secured worm-wheels O andvO in mesh with worms O2 and O3, secured on longitudinallyextending shafts O4 and O5, journaled in suitable bearings on the front and rear sides of the vat A. The shafts O4 and O5 are provided with bevel gear-wheels OG and O7, of which the bevel gearwheel O6 is adapted to bed engaged on alternate sides by either a bevelpinion P or a bevel-pinion P, secured on a transversely-extending shaft P, journaled in suitable bearings attached to the right-hand side of the vat A. Similaipinions P3 and P", secured on the shaft P2, are adapted to engage opposite sides of the bevel gear-wheel O7, and the said shaft P2 is provided with a sprocketwheel P5, connected, by a sprocket-chain P, with a sprocket-wheel P7, secured on the shaft H2 of the circulating-pump, so that when the machine is in operation a rotary motion is given to the shaft P2, which by either of the sets of bevel-pinions P P2i or P P4 imparts a forward or backward rotary motion to the bevel gear-wheels O and O7 and their shafts O* and O5. Thus when the shaft P2 is shifted transversely from the front toward the rear then the pinions P and P3 move in mesh with the bevel gear-wheels O6 and O to rotate the shafts O* and O5 in one direction, and when the shaft P2 is shifted transversely from the rear toward the front then the bevel-pinions P and Pi move in mesh with the bevel gearwheels O5 and O to rotate the shafts O4 and O2 in the opposite direction. ANormally, however, the bevel-pinions P, P, P2, and P4 are out of mesh with the bevel gear-wheels O6 and O7, as plainly indicated in Fig. 5, and consequently the shafts O2 and O5 are at a standstill. When the bevel-pinions P and P3 are in mesh with the bevel gear-wheels O and O7 and the shafts O* and O2 are rotated in one IOO IOS

IIO

direction, then the worms O2 and O2, secured on the said shafts, rotate the worm-wheels 0 and O, and consequently the drums N and N to wind up the ropes or chains L and L to lift the right-hand side of the false perforated bottom B, and when the pinions P and P" are in mesh with the said bevel gear-wheels O and O2 then the drums N and N are rotated in an opposite direction to lower the righthand end of the false bottom B. Now the drums N2 and N2 rotate in unison with the drmns N and N to lift the left-hand end of the false bottom B simultaneously with the lifting' of the right-hand end thereof, as above mentioned, until the false perforated bottom B reaches the top of the vat A, and when the false perforated bottom reaches this position then the rotation of the drums N2 and N2ceases, while the drums N and N keep on rotatingto swing the Afalse perforated bottom B into an inclined or discharging' position, as shown in Figs. l and 2, the connectingends of the ropes L2 and L2, with the false perforated bottom B, then serving' as a fuicrum for the said bottom to swing' on. In order to accomplish this result, the following device is provided: On the shaft O (see Figs. 1 and 5) is secured a clutch member Q, adapted to be engaged bya clutch member Q, secured on a longitudinally-ektending' shaft Q2, journaledA in suitable bearings attached to the front side of the vat A. On the shaft Q2 is secured a worm Q2in mesh with a worm-wheel Q, fastened on the shaft N" adjacent to the drum N2, so that when the shaft is rotated the worm Q2 and wormwheel Qt impart a rotary motion to the shaft N and consequentlyT to the drums i\2 and N2, secured on the said shaft. Now the clutch member Q is mounted to slide on and to turn with the shaft Q2, and the said clutch member is engaged by a shifting-lever Q2 for moving the clutch member Q in and out of engagement with the clutch member Q, secured on the shaft O, as above mentioned. The shifting-lever Q2 is pivotally connected with a spring-pressed sliding bar Q", pivotally conneeted with an arm Q2, having' a curved end Q2 (see Figs. l1 and 12) engaging the peripheral face of a spiral cam Q2, secured on or forming part of the drum N.

Now when the false bottom B is in working position in the vat A and it is desired to lift the said bottom out of the vat and then swing it into an inclined position for discharging the dyed material then the shaft P2 is shifted to bring the pinions P and P3 in mesh with the bevel gear-whee1s O2 and OT for turning the shafts C)l and O"l and the drums N and N', as previously described, and at the same time the shaft is turned from the shaft O, as at this time the clutch member Q is in mesh with the clutch member Q. .lhe curved end Qs at the beginning of the rotation of the drum N is in engagement with the small end of the cam Q2 to hold the Clutch member Q in engagement with the clutch member Q. During the. time the clutch members Q and Q are in mesh with each other the several drums N, N, N2, and N3 are rotated in unison to wind up their ropes or chains L, L, L2, and L2 for lifting' the false perforated bottom B in the vat A, and when the said bottom has reached the top of the vat then the cu'rved end Q2 of the arm QT travels on the large end of the cam Q" to impart a swinging motion to the shifting-lever Q2 to move the clutch member Q ont of mesh with the clutch member Q. lVhen this takes place, the rotation of the shaft Q2, and consequently that of the drums N2 and N2, ceases, while the rotation of the drums N and N proceeds for the ropes or chains L and L to pull up the right-hand end of the false perforated bottom B-that is, to swing the same into an inclined discharging position for dischargingthe dyed material to one side of the machine. rhen the false perforated bottom B reaches the desired inclined position, (described and shown in Figs. l and 2,)then the shaft P2 is shifted automatically in a transverse direction from the front to the rear to move the pinions P and P2 out of mesh with the gear-wl'ieels O and O7. fhen it is desired to return the false perforated bottom B back into the vat for dyeing another batch of materiahthen the shaft P2 is shifted transversely from the rear toward the front to move the pinions P and PL into mesh with the bevel gear-wheels O and OT for rotating the shafts O" and O and their drums N and N to unwind the ropes or chains L and L. The latter now lower the right-hand side of the false perforated bottom B until the latter assumes a horizontal position at the upper end of the vat A, and when this takes place the shifting`lever Ql is actuated b v the arm Q7 and cam QJ to again move the clutch member Q in mesh with the clutch member Q,so that the shaft Q2 is now rotated. and with it the drums N2 and N 2, for unwinding the ropes or chains L2and L2. As the several drums N, N, N2, and N2 now unwind their ropes or chains in unison, it is evident that the false perforated bottom B is lowered in the vat A until it finally rests on the lugs A2. W'hen this position is reached, the shaft P2 is shifted transversely from the front toward the rear to move the pinions P and P* out of mesh with the bevel gear-wheels O and OT, so that the rotation of the shafts Ol and O2 and that of the shaft Q2 ceases.

ln order to automatically shift the shaft P2 in the manner described, the-following automatic device is provided, special reference being had to Figs. T, 8, and 9: On the shaft P2 is secured a shifting collar R, engaged by a shifting-lever R', pivotally connected with the eccentric-rod R2 of an eccentric R2, having its shaft RL journaled in suitable bearings attached to the vfat A. On the shaft R1 is secured an arm R", carrying at one end a weight IOO R5, to automatically swing the arm R5 when released, as hereinafter described, from a horizontal position into avertical position, thereby turning the eccentric-shaft R* for the eccentric to actuate the shifting-lever R to move the shaft P2 either from the front toward the rear or from the rear toward the front, as hereinafter more fully described. The arm R5 when swung by the operator into a horizontal position either to the right or to the left is adapted to be engaged with a notch formed in the end of a slide R7, mounted to slide longitudinally in suitable bearings carried by the vat A, at the rear side thereof, and the said slide R7 is pressed on by a spring Rs to normally hold the slide in engagement with the arm R5. Thel slide R7 is pivotally connected with a cam-arm R5, having its curved end R10 (see Fig. 8) in peripheral engagement with a spiral cam Ru, secured on the shaft N5. Vhen it is desired to lift the false perforated bottom B out of the vat A and to swing the same into the discharging position previously mentioned and shown in Figs. l and 2, then the operator swings the arm R5 from its normal vertical position shown in Fig. 6 to the right (see dotted lines, Fig. 7) until the arm is in a horizontal position and in engagement with the notch in the slide R7. Now by moving the arm R5 into this position the shaft P2 is shifted from the front toward the rear to move the bevel-pinions P and P3 in mesh with the bevel gear-wheels O5 and O7 to rotate the several drums N, N N2, and N 2, as previously explained, for the ropes or chains to wind up on the said drums. When the false perforated bottom B has reached the top of the vat, then the shaft Q2 is thrown out of gear, as previously explained, so that the drums N2 and N3 cease to rotate, while the drums N and N' keep on rotating until the false perforated bottom B has reached the inclined discharging position shown in Figs. l and 2. When the false perforated bottom B about reaches this position, then the cam-arm R9 is moved longitudinally from the right to the left by the cam R11, so that the slide R7 is drawn from the right to the left against the tension of the spring R8 and out of engagement with the arm R5 to allow the weight R5 thereof to swing the arm back into a vertical position. In doing so the shaft P2 is shifted transversely from the rear toward the front to move the bevel-pinions P and P5 out of mesh with the bevel gear-wheels OG and O7, and consequently the rotation of the drums N and N now also ceases. When it is desired to return the false perforated bottom B back into the vat, then the operator swings the arm R5 to the left, as shown in full lines in Figs. 7 and 9, until the arm reaches a horizontal position and engages the notch in the slide R7. By moving the arm R5 in this position the shaft P2 is shifted to move the bevel-pinions P and P2 into mesh Aor chains L and L.

bottom is now lowered in the vat A, and when with the bevel gear-wheels O5 and O7A to rotate the shafts O'i and O5 in a reverse direction for the drums N and N' to unwind their ropes or chains. When the false perforated bottom B reaches its horizontal position on the top of the vat A, then the clutch member Q is thrown in mesh with the clutch member Q, for n ow starting the drums N2 and N3 in a reverse direction to unwind the ropes or chains L2 and L3 simultaneously with the ropes The false perforated it about reaches the lugs A2 the cam-arm R5 is acted on by the cam Rl1 to withdraw the slide R7 for the arm R5 to swing back to its vertical position and to thereby move the shaft P2 transversely from the front toward the rear to move the pinions P and P2 out of mesh with the bevel gear-wheels O5 and O7. The rotation of the shafts O5 and O5 now ceases.

As indicated in Fig. 5, the corners of the cover D are cut out to allow a ready passage of the ropes or chains L, L, L2, and L5.

Y It is understood that the cams Q9 and R11 i are so arranged as to properly actuate the corresponding parts Q7 and RD at the proper time and as above described.

The shifting of the shaft P2 in a transverse direction does not affect the position of the sprocket-wheel P, as the shaft P2 has a key engaging a keyway in the sprocket-wheel P5, held against transverse movement by bearings on opposite sides of its hub.

The weight R5 on the arm R5 is preferably provided with a spring-catch R12 to lock the arm to the vat at the time the arm is in the vertical position shown in Fig. 6.

In order to move the cover D out of the way when raising or lowering the false perforated bottom B and for vertically adjusting the said cover to properly engage the top of the material C, the following device is provided: The cover D is hung on a plurality of racks S, in mesh with pinions S', secured on shafts S2, extending longitudinally and journaled in suitable bearings attached to a swingframe T, the said racks S being held in engagement with their pinions by friction-rollers S2, journaled on the swing-frame and en' gaging the backs of the said racks. Each of the shafts S2 is provided with a worm-wheel S2, in mesh with a worm S5, secured on a shaft S5, extending transversely and journaled in suitable bearings attached to the upper end of the right-hand side of the vat A, as plainly illustrated in the drawings. The shaft S5 forms the fulcrum for the frame T to swing on, and on the said shaft S5 is secured a handwheel S7, adapted to be taken hold of by the operator for turning the shaft S5 to impart a rotary motion to the shafts S2 and their pinions S for moving the racks S upward or downward with the cover D, according to the direction in which the hand-wheel S7 is turned. The free end of the swing-frame T is connect- IOO ed with one end of a rope or chain T, extending upwardly in an inclined direction and passing' over a pulley T2, journaled on the overhead frame Ai previously mentioned. A connterweight T3 is secured on tbe rope T for conveniently swinging the swing-frame T from the normal horizontal position shown in Fig. 3 to the vertical position shown in Figs. 1 and Q. Normally the swing-frame T is locked in its horizontal position b v a springcatch TL of any approved construction and arranged on the free end of the swing-frame, the said spring-catch being adapted to engage a suitable keeper T", fastened to the upper end of the left-hand side of the vat A. (See Fig. 3.) The spring-catch T'i is preferably in the shape of a bolt (see Figs. 3 and 13) pressed on by a spring T and mounted to slide in suitable bearings on the swing-frame T. The inner end of the bolt is pivotally connected with a tripping-lever T7, fulcrumed on the swingframe and adapted to be engaged by a wedge T", secu red to or formed on one of the racks S. Now when the cover D is raised and the wedge TS engages the tripping-lever (sec Fig. 13) the bolt is withdrawn, and hence the swing-frame is automatically unlocked. The wedge Ts holds the bolt in a withdrawn position until the cover is again lowered at the next operation, it being understood that when the wedge Ts moveslout of engagement with the tripping-lever T then the spring' T moves the bolt outward into engagement with the keeper T. Then the spring-catch T" is disengaged from its keeper T'i, as above described, then the counterweight T:s imparts an upward swinging motion to the frame T, on which the cover l) is suspended, by the racks S engaging tbe pinions S. It is understood that the swing-'frame T when locked in its horizontal position is not swung upward into a vertical position until the cover D has first been raised close up to the swing-frame by the operator turning the hand-wheel ST correspondingly"that is, not until the cover l) practically out ol the upper end of the vat and the swing-frame T is automatically unlocked, as above described.

The operation is as follows: ln starting, the valve is in a lowermost position, (see Fig. 3,) the valve H-l is open, and the valve J' closed, and the shaft P? is in the intermediate position, with the weighted arm PU'l locked in a vertical position. The material-say a bale of cotton in loose conditionv-to be dyed is placed into the empty vat at the time the false perforated bottom B rests on the lugs A and the cover D and its supporting-frame are in an uppermost vertical position. After the material is in place on the false perforated g bottom B the frame T is swung downward i into a horizontal position, and then the operator turns the hand-wheel ST to move the cover 1,) down into firm contact with the top l of tbe material to confine the same in the vat between the false perforated bottom B and the said cover D, as shown in Figs. 3 and et. Tater is now run into the vat A from any suitable source until the water flows into the top of the overflow-pipe E and lills the same. so that the level of the water is about `flush with the top of the overflow-pipe E. Steam is now admitted to the pipe or coil l( to heat the water approximately to the boiling-point. The engine H"i now started to rotate the shaft P2 and to actuate the circulating-pump H Afor the latter to draw the water out of the overflow-pipe E and force the water, by way of the pipes l and nozzles I. into the circulating space or chamber A: for the water to move in a circular path around the well F and force the dirt'from the material or other extraneous matter into the well F. The water also rises through the perforations in the false bottom B and through the material C and the perforations in the cover D to linally flow back into the overflow-pipe E to be returned to the circulating-space A3 by the circulating'- pump. The dissolved dyestutl'l is added to the water in the tank to forni a dye liquor, which is now circulated through the vat A and the material (l, the same as the water and as above described. This operation is continued until the dye liquor has dyed the material and is su tliciently exhausted to warrant its removal, which is done as follows: The circulating pump H is temporarily stopped and the valve (1 is raised until its port (i is in register with the well-pipe F2 to allow the liquor in the overflow-pipe l@ to drain ont at the seat (if. The valve H" is now closed and the valve J opened and the cireulating-pump ll is restarted to draw the dye liquor from the vat A by way of the well F, pipe F2, and valve and force it up the pipe J into the overhead storage-tank J" for further use. The valve J is then closed. W'hen the vat A is empty of the dye liquor, the valve is again moved into a lower-most position and water is again run into the vat A and circulated through the material C until the latter is thoroughly rinsed. The valve (H is now raised to an uppermost position-that is, until thebottom of the valve G' clears the pipe F to allow the water to completely drain the vat A, the overflow-pipe E, and the well F. The operator now turns the hand-wheel S' in a'reverse direction to lift the cover D into its uppermost position for the catch T to automatically disengage its keeper T to allow the frame T, and with it the cover D, to swing into a vertical position by the action of the counterweiglit TJ and the assistance of the operator. The weighted arm R5 is now unlocked and swung upward toward the right,as indicated in dotted lines in Fig. T,to shift the shaft P2 until the pinions Pand P are in mesh with the bevel gearwheels O" and O7 for rotating the several drums N, N, N2, and Ns to simultaneously IOO wind up the ropes or chains L, L, L2, and L3 to raise the false perforated bottom B and the dyed material (l thereon until the said bottom reaches the top of the vat. The drums N2 N3 are now thrown automatically out of gear by the shifting of the clutch member Q, as previously explained, so that Ithe false perforated bottom B now swings into an inclined discharging position for the dyed material to slide off the said bottom to one side of the machine into a suitable support, receptacle, or other device. When the false perforated bottom B reaches its discharging position, the arm R5 is automatically released and swings back to its normal vertical position to shift the shaft P2 to its intermediate position, and the drums N and Nl now cease to rotate. When it is desired to return the false perforated bottom into the vat A, the arm R5 is swung over to the left (see Fig. 9) to run the drums N and N' in a reverse direction until the false perforated bottom has reached a horizontal position on the top of the vat, and then the drums N2 and N3 are set in motion to lower the bottom B into the tank. The above-described operation is then repeated for dyeing another batch of material.

Having thus described my inventionl claim as new and desire to secure by Letters Patentd l.
